IMPROVEMENT IN STRIPPING ATTACHMENTS T0 CARDlNG-MACHINES.

Specific-ation forming part or Letters Patent No. 206,510, dated July30, 11378; application filed March 2, 1878.

To all whom it may concern:

Be it known that we, MARCIENE H. VIIIT- corn; and JOHN Brass, ofHolyoke, in the county of Hampden and State of Massachusetts, haveinvented anew andImprovedvStrpping Attachment to Garding Machines, ofwhich the following. is a specification:

In the accompanying drawing, Figure l represents a vertical longitudinalsection of our improved stripping attachment to earding-maehines on linew, Fig. 2; and Fig. 2 is a top view of the same.

Similar letters of reference indicate corresponding parts.

This invention relates to an improved stripping attachment towool-earding machines by which a positive and perfectly sure strippingof the sliver is obtained in such a manner that it does away with therattling noisy combs, and the liabilityr of damage which always attendstheir use.

The improved attachment accomplishes better work on account of its morepositive and perfect action, produces less waste, and obviates reworkingof the stock.

The invention will first be described in connection with the drawing,and then pointed out in the claim.

Referring to the drawing, A represents a section of the main cylinder ofa finisher carding-machine, andB the dotter working in connectiontherewith. The stripping attachment that serves for taking up the sliverfrom the doifer is composed of three rolls, C, D, and E, which take upthe sliver from the dotl'er, in the manner shown in Fig. 1, in acontinuous black line, the sliver passing instead of under the roll, asin the present earding-maehine, over the top part of the roll C, andthence to the outer auxiliary roll E, and from the same to thecondensing rolls, and finally to the winding -frame. The roll C is thestripper proper, which takes the stock or sliver from the dofferB, thespeed of this roll being slightly less than that of the doffer. Thedoffer and stripping-roll are set only about one sixtyfourth ot' an inchapa-rt, so that the stock on the doffer must be left on the stripper,which runs in an opposite direction to the doffer, as indicated by thearrows in Fig. 1. Instead of bein g covered with short conical points,as the usual strippers, the roll C is clothed with the same long wire asthe doffer itself. Therolls D andE are auxiliaries to the stripping-roll, the roll D being covered with points about one-halt' an inch inlength, placed above the roll G and set lightly into the doffer. Itserves to keep the wire of the same clear of steek or dirt. It alsokeeps the points of the dofler-roll clear and in working order, by neverallowing them to till, which would deprive them of the power to take thestock or wool from the carding-eylinder A. The auxiliary roll D alsoserves to keep the points of the doffer sharp andpointed. The secondauxiliary roll,E, is arranged at that side of the stripping-rollopposite to the doffer, and covered with short points, which remove thestock or sliver from roll C, lifting it lightly from the stripper, so asto be easily taken therefrom and delivered to the condensingrolls.

The stripping-rollC takes up the web at its upper part, so as to lift itfrom the doffer without the least strain upon it, instead of drawing theweb from the doifer by the strength of the ber, as in the oldcarding-maehine. The web is thereby supported so lightly on thestripping-roll that a breath almost will remove it, which function isaccomplished by the auxiliary roll F that takes up the web with theshort teeth.

The advantages of our improved stripping attachment are that theoperation is positive and cannot fail to do its work. doffer to be runat a very high rate of speed when workin g short stock, while, when alarge sliver must be made, it allows the machine to work freer byremoving the stock from the machine faster, while the stock is massed onthe stripping-roll, so as to govern the size ot' the sliver to such anextent that much better cardin g and less strain on the card-clothing isexerted. No interruptions by causing the sliver to work in between thestripper and the doft'er can occur, so as to give bad work and occasiondelay. It does away with the rattling combs in both finisher and breakercards, does not shake the machine and floor, and requires small power todrive it. -It is easily adjusted and unfailing in operation, therebydoing better work than with the old devices.

Another advantage is that much shorter nrren,

It allows the stock can bc used, as the saine is Worked upon without anystrain on the iber7 taking up the web by the picking or liftingoperation of the stripping-roll without the least strain or violentmotion on the web, so that stock with Very short ber may be successfullyhandled by our improved attachment.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- In a finishing carding-machine, thecombination of the doier B and stripper C, the stripper clothed withlong wire, and turning in an opposite direction from and moving at aslower speed than the doer, thus carrying the sliver over the roll C,for the purposes de- 1 scribed.
